IMPROVEMENT IN DmvINc-BANDS FOR MACHINERY..

Specification forming part of Letters Patent No. 36,110, dated August-5, 1862.

To @ZZ whom it may concern.-

Beit known that I, CHARLEs M. ROULLIER, of Paris, in the Empire of France, have in vented certain new and useful Improvements in Cables or Belts or Bands; and I hereby declare,

the following to be a full, clear, and exact description of the same.

The object of my invention is to utilize theY y tute a cable or band capable of adjustment in length and Width without seam or ridge, substantially as hereinafter set forth.

The width of the cable or belt depends upon the number 0f links placed one against the other. rlhe pins or bolts passing through either end of the links are of a length varying with the width of the belt or cable. Thus the width of each link constitutes the thickness of the belt or cable, and the union of the thicknesses of links, held together by one and the same bolt or pin, constitute the width of the cable or belt. The pins Or bolts uniting the links are riveted at their extremities and upon the outer sides of the belt, or they may be threaded and have their heads screwed onto them. The latter are used for the adjustment of the cable as to length and width. If it be necessary to reduce or increase the length of the cable, one or more rows of links are removed or added. If the belts or bands in their operation are destined to cross each other, I cover the outside with a continuous band, so to avoid the hooking of the parts together and breaking or tearing the belt.

In machinery or apparatus in which the belt or cable is exposed to great strain-such as in suspension-cables-the leatherlinks may be alternated by links of metal, thereby preventing the tearing of the holes in the leather links, or metal links may be placedin the center or at the outside of or otherwise arranged in relation to the leather links. The same Object vwill be attained by applying to each face Of the leather link a thin plate of zinc,

iron, copper, or other metal. It is obvious that as to form and dimension the links may be varied according to necessities of manufacture.

In the accompanying drawings I have show my improved cable or chain* Figure 1 representing an articulated cable or band, A, mounted upon two pulleys or drums, B and C.

Fig. 2 is a side view showing the thickness of a fragment of my articulated belt A.

Fig. 3 is a plan view of part of the same belt, showing it in its width. This width is variable, and is obtained by the union of several thicknesses Of links D, placed one against the other in an upright position and bolted together or riveted through. by one and the same bolt or pin, E.

Figs. 4 and 5 represent an individual link D, showing its dimensions and form upon all sides. This link is cutout of a Waste piece of leather.

Fig. 6 is a spindle, E, with rivet-heads.

Fig. 7 is a detail representation of a spindle, E', used for the adjustment of the belt Or cable. It is provided with a threaded end and a corresponding threaded nut, F.

Figs. 8 and 9 arev views in elevation and plan of a part of cable which, being provided with side bands, G, is or may be used in cases where the bands or cables have to cross each other; and, lastly, Fig. 10 represents a link placed upon its sides H, for the purpose of strengthening it to resist great strains.

Having thus described my invention and the manner in which the same is or may be carried into effect, I claim- As a new manufacture, the production of articulated cables, bands, or belts for driving machinery Or forv other purposes by utilizing Waste cuttings of leather and forming such cuttings into links, which, being mounted upon spindles, whether combined or not with metallic links, constitute a cable or band capable of adjustment in length and width Without seam or ridge, substantially as herein set forth. v In testimony whereofI have signed my name to this specification before two subscribing Witnesses.
